Thus, our comparison of the paranoid SZ and SAD patients complies with a standard method
of costing implemented in Germany. According to the „Costs accounting manual“, the daily
inpatients costs consist of eight cost category groups:personnel costs physician service;
personnel costs nursing service; personal costs, medical technical service/function service;
material cost pharmaceutical products; material costs pharmaceutical products, direct
costs; implant and grafts; material costs; other medical material costs; personnel
and material costs medical infrastructure and personnel and non-material costs medical
infrastructure. To provide an overview, we tested for differences between the mean total costs
as well as differences of partial costs i.e. mean costs for medication products , mean
personal costs and mean infrastructure costs for the statistical analysis. Note that
these partial costs do not add up to the amount of total costs, since we did not compare items
, which have only very small contributions to the overall costs.
